GUIDE-BOARD.

SPECIFICATION OTITIng'pIt of Letters Patent No. 354,303l dated December14, 1886.

Application filed April 19l 1884. Serial No. 128,539.

To aZZ whom t may concern.-

Be it known that I, WILLIAM W. CASE, of Baptistown, in the county of'Hunterdon and State of New Jersey, haveinvented a new and ImprovedGuide-Board, of which the follow ing is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the gures.

Figure lis a sectional elevation of Iny invention. Fig. 2 is a sectionalplan view taken ontlie line x .r of Fig. l. Fig. 3 is a sectionalelevation of the guide-board proper, taken on the line y y of Fig. l.Fig. 4 is a front elevation of one of the holding-plates removed fromthe headblock. Fig. 5 is a front elevation of the clamp-plate, and Fig.6 is a sectional elevation showing a modification ofthe guide-boardproper.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

A represents the post set in the ground and braced by the bottom plate,a, and surfaceplate b, through which latter the rods d are passed anddriven into the ground.

c is a covering-plate for covering the upper ends of the rods (Z. v

To the upper end of the post A is secured the flanged cap B,of iron, andthe vertical bolt C, which passes up through the center of the cap B. rIhe upper portion, c', of the bolt is Inadesmallerthanthelower portion,c2. Upon the lower portion, c2, of the bolt Gis placed the cast-ironhead D, which is held securely in place by the nut e, screwed upon thecentral Screw-threaded portion, e', ofthe bolt. In this instance thehead Dis made octagonal in form, and in each of the faces thereof isformed a dovetailed or other recess, f, to receive the bevel-edgedShanks g of the flanged holdingplates E. These holding-plates E,ybesides be- I ing formed with the said shanks g, are formed with theclaw flanges or rims g g', for receiving the edges or flanges hh of theclamp F, in which is placed the end of' the guide-board proper, G, andat their upper ends the holding-plates E are formed with the studs g2,which are adapted to pass through orifices made in the cap-plate (Nomodel.)

are made of sheet metal or other suitable mav terial, and are slippedinto the undercut flanges Z Z from the end of the board next to the postA `before the clamp-plate F is put in place. At its outer end theguide-board G is formed or provided with the pointer or index G.

Constructed in the manner described,it will be seen that the guide-boardis strong, practical, and durable, and that the board Gniay be set topoint inl any direction required, will always be held firm and rigid,and that the guideboard as a whole presents a nice and attractiveappearance.

The cap-plate c on the surface of the ground is intended tol be fasteneddown with a key.

I design in some cases to form the guideboard G with the centrallongitudinal undercut or dovetailed ribs, Z Z, as shown in Fig. 6,adapting the board to receive double sets of letters upon both sides ofthe board, and I design to coat the letters with luminous paint, so thatthe guide-board will be visible at night. When placed at cross-roads,the head D will have several guide-boards connected therewith, accordingto the number of roads.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. In a guide-board, the combination, with ahead having a vertical dovetail recess, of two clainpplates havingvertical flanges on their rear edges engaging the said dovetail recess,and a sign-board held between the said clampplates, substantially as setforth.

2. In a guide-board, the head D, formed with one or more dovetailedrecesses, f, in conibination with the holding-plates E, engaging saidrecesses, clamp-plates F,held by said holdfoo , ing-plates, andguide-board G, secured by said clamp plates, arranged substantially asdescribed.

3. In a guideboard, the combination, with the recessed head andapertured cap-plate, of the holding-plate E, formed with the shank g,engaging the recessed head g', and stud g2, entering the aperture in thecap-plate, as and for the purposes set forth.`

4. rIhe combination, with the recessed head D and the clamp-plate F,held thereon and provided With the pin j, ofthe signboard having anaperture, k, through which pinj passes, and

anges l, open at their rear ends, which abut against the clampvplate,andremovable letters Within said flanges, whereby when pinj is With drawnthe sign-board may be disconnected and the letters removed,substantially as set forth.

5. The guide-board G, provided with the clamp-plate F, in combinationwith the flanged holding-plate E, with which the said clampplate isconnected, and the head D, to which the holding-plate E is secured,substantially as described.

6. rlhe combination, with asign-board, of a post, tubular flanged cap Bthereon, the head D, to which the sign-board is secured, having acentral aperture, the bolt G,passed up through the cap B and head, andthe nut e, securing the head and cap together, substantially as setforth.

A7. In a guide-board, the cap B, the bolt C,-

passed through the cap and formed `with the upper reduced portion, c',and larger lower portion, c2, threaded at e', in combinationwith therecessed head D, through which part c2 passes, nut e, screwed upon thescrew-threads e', and holding the head to the cap B, the upper aperturedplate, H, the holding-plate E, held to the head and plate H, and the topnut, fi, on the bolt, and securing said plate and the holding-plate inposition, as and for the purpose set forth.

8. The post A, provided at its upper end with the fianged cap B, and thebolt @,passing through the cap, in combination with thehead D, formedwith dovetailed recessesf, the holdingplates E,held in the recessesf,the clampplate F, the guide-board G, the top plate, H, and the nuts eand i, all arranged substantially as and for the purposes set forth.
